摘　　要：根据稳定性分析的前屈曲完全理论和修正型的Hahn－Tsai非线性本构关系，利用有限元位移法，对复合材料锥柱结合壳进行了考虑材料非线性弹性性能的总体稳定性分析，考察了复合材料的横向和剪切非线性对结构总体稳定性的影响．This paper investigates the global stability analysis for laminated composite coner-cylindrical connected shells using finite element method in consideration of nonlinear elasticity behaviour of composite materials. The modified Hahn-Tsai nonlinear constitutive relationship is applied. The initial stress state of the shell in the prebuckling state is obtained by complete shell theory. The effect of transverse and shear nonlinearity on the global stability for the shells under axial compression and lateral external pressure is also studied.
